RENSSELAER KNAPP, OF GLENS FALLS, NEW YORK.

vIMPROVEMENT IN BUCK-BOARD WAGONS.

Specification forming part of Letters Patent N0. 155,451, dated September 29, 1874; application filed August 25, 1874.

To all whom it may concern:

Be it known that I, RENssELAEE KNAPP, of Glens Falls, in the county of Warren and State of New York, have invented a new .and valuable Improvement in Buck-Board Buggies; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a plan view of my buck-board buggy. Fig. 2 is a bottom view, and Fig. 3 is a sectional view, of the same.

This invention has relation to buck-boards for wagons or buggies; and the nature of the invention consists in combining with a buckboard, which may be of one piece, or consist of a number of slats, a spring, which is secured to the said buck-board at each of its longitudinal edges, whereby I am enabled to construct the buck-board of thin stud' and secure a more complete and equal yielding thereof to shocks occasioned byinequalities in a road. It also consists in a batten applied transversely to the buck-board at or near the middle of its length, to which batten are secured the sustaining-springs, whereby the said board is braced when under strain, and, when slats are used instead of a single piece, serves to prevent lateral displacement thereof, all as will be hereinafter more fully explained.

In the annexed drawings, A designates my improved buck-board, having a suitable upward curvature, which is rigidly secured to two transverse bolsters, B B', of a wagon. These bolsters are secured to the sand-bars in front by means of a king-bolt, and in rear by a number of bolts and nuts, in the usual wellknown manner.

On account of its superior toughness and elasticity, I prefer to use the timber of the rock-elm tree in the construction of my buckboard, but do not confine myself to `any special variety. I also use, instead of a single board, a number of slats, which are, in like manner, secured to the bolsters B, and are prevented from lateral displacement by means of a batten, a, which is applied, at or near the middle of their length, to the under sides, both of the slats and single board.

S S designate curved metallic springs of such length that, when they are rigidly secured at the middle of their length to the batten a, their ends shall extend nearly to the ends of the buck-board A, as shown in Fig. 1. These springs are applied at each of the lateral edges of the buck-boards, and each of their extremities is provided with a hook, b, for a purpose hereinafter to be explained.

In the drawings these springs are represented as consisting of several scales superposed, the one above the other, and suitably bolted together; but they may be constructed of a single piece of steel Where such a variation would prove desirable.

C designates hooks, having sbanks c, by means of which they are rigidly secured to the under side of the buck-board A at or near its front and rear ends. These hooks receive links d, preferably of rectangular form, into which are secured the hooks b upon the ends of the springs S S', by means of which the said springs are removably applied to the buckboard.

It will be seen that, by means of the springs S S', I have been enabled to construct the buck-board of thin materials, and consequently have greatly lessened the Weight to be borne by the wheels; also, Jthat the yielding of the said board has been made more regular and easier; and, finally, that,l by the application of a batten to the under side of the slats, I have prevented lateral spread thereof and afforded a brace by which the springs are more durably secured to the buckboard or to the slats.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a buck-board for wagons, the combination of the sustaining-springs S Sl and hooks C with the buck-board A, substantially as specified.

2. The combination of the batten a with the buck-board A, springs S S', and hooks C, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the Lpresence of two witnesses.
